TI's Class-D stereo amplifier produces size-defying sound for ultrabooks, Bluetooth speakers, and tablet and ultrabook docking stations. The TPA3131D2 is the industry's first Class-D amplifier to deliver 7W from a miniature QFN package. It produces more than three times the power output compared to high definition audio codecs, and it's half the package size of discrete amplifiers with comparable output, while delivering longer standby battery life.

DALLAS, Oct. 31, 2013 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today introduced a Class-D stereo amplifier that produces size-defying sound for ultrabooks, Bluetooth® speakers, and tablet and ultrabook docking stations. The TPA3131D2 is the industry's first Class-D amplifier to deliver 7 W from a miniature QFN package. It produces more than three times the power output compared to high definition audio (HDA) codecs, and it's half the package size of discrete amplifiers with comparable output, while delivering longer standby battery life. For more information and to order samples, visit www.ti.com/tpa3131d2-pr.

Size-defying sound: 7-W stereo output provides more than three times the power output of 2-W HDA codecs, enabling louder, crisper sound from ultrabooks and Bluetooth speakers.

Package fits ultrabooks: The 5-mm by 5-mm QFN package is nearly half the size of discrete amplifiers in TSSOP packages. It simplifies board layout for designers and delivers the highest power output per square millimeter of board space.

Longer battery life: Up to 92-percent power-efficientClass-D operation, and less than 50-uA quiescent power consumption allows for longer standby battery life compared to discrete amplifiers in larger TSSOP packages.

Tools and supportThe TPA3131D2EVM can be purchased today for a suggested retail price of US$149. PSpice models are also available for verifying board signal integrity requirements.

Technical support is available on the Audio Forum in the TI E2E™Community, where engineers can search for solutions, get help, share knowledge and solve problems with fellow engineers and TI experts.

Availability and pricingThe TPA3131D2 is available today in a 32-pin QFN package for a suggested retail price of US$1.10 in 1,000-unit quantities.
